Course Description and Learning Objectives
This course introduces students to chemical principles with applications in engineering. Topics
covered include stoichiometric calculations, properties of gases, properties of liquids and solutions, gas
phase chemical equilibrium, ionic equilibrium in aqueous solution, oxidation-reduction reactions and
chemical kinetics. By the end of the course students should be able to:

Explain the behaviour of ideal systems (including different states of matter, physical and
chemical equilibrium and reaction kinetics) in terms of the molecular nature of matter.

Write balanced chemical reactions and perform stoichiometric calculations.

Apply the Ideal Gas Law while appreciating the limitations of this law.

Identify which principles of physical chemistry are relevant to the analysis of problems
involving physical and chemical equilibrium and rates of reaction.

Select and apply an appropriate law to solve problems described above and explain his/her
reasoning to others in the field of chemistry and/or chemical engineering.

Textbook
General Chemistry: Principles and Modern Applications, 10th Edition, 2010. R.H. Petrucci, F.G.
Herring, J.D. Madura, and C. Bissonnette. Pearson Canada Inc., Toronto, Ontario.
The previous edition (9th) is also acceptable. Second-hand copies of both new and old editions are
readily available.
If you purchase the textbook new from the bookstore, it will come bundled with Mastering Chemistry
(a set of online problems and access to the e-textbook) and an iClicker voucher (a $10 mail-in rebate
that also requires you to buy the clicker in the same transaction as the chemistry textbook); the
bookstore has indicated that there is no additional charge for these beyond the regular textbook price.
It is also possible to rent (note, not a permanent purchase) solely an electronic copy of the textbook at a
significantly reduced price. However, you should be aware that you may not be able to return an etextbook for refund, that access is provided for a limited period only (your access will probably expire
shortly after the end of term) and that you cannot later sell access to an e-textbook (while you may be
able to sell a physical copy of the textbook). If you are still interested, the electronic version is
available at: http://www.coursesmart.com/IR/2737759/9780135097755?__hdv=6.8
iClickers
Some instructors make use of iClickers in this course. If you require an iClicker, your instructor will
inform you of this on the first day of class.

Tutorials
Two-hour tutorials will take place every week. At the beginning of tutorial the TA will discuss
common misconceptions and difficulties stemming from the previous week’s assignment and lectures.
During the remainder of the tutorial you will work in small (2-3 students) groups to complete a tutorial
quiz. You will submit one quiz per group and receive a grade based on completion. For a small number
of tutorial sessions this term you will explore chemistry concepts through an Engineering IDEAs
Clinic activity.
Homework Assignments
Homework assignments are designed to reinforce content covered during the weekly lectures. These
assignments will be administered using Maple T.A. and can be accessed through Learn. Instructions
for accessing and using Maple T.A. are posted on Learn in the “Information for All Students” section.
Please note that Safari and Google Chrome are not supported browsers for Maple T.A. Assignments
will typically be available on Friday and due the following Thursday. Sample solutions to the
assignments will be posted on the course website the week after the assignment is completed.
Examinations
Examinations are multiple choice. Samples of previous examinations with correct answers will be
posted on Learn for practice. Complete worked solutions to these sample exams will not be provided.
During exams (both midterm and final) students are allowed to consult one letter-sized (8½” × 11”)
sheet of paper, either hand- or typewritten on both sides with any information they consider relevant.

Holidays
The University will be closed on Monday October 12th for Thanksgiving Day.
To make up for the missed class time, Saturday November 21st will be a class day following a Monday
schedule (see https://uwaterloo.ca/quest/undergraduate-students/important-dates/important-dates-20152016).
Software Engineering students: you will make up your missed tutorial session from Monday
October 12th on Monday October 19th (which is during mid-term week for first-year students).
Therefore there will be no tutorial session for ChE102 on Saturday November 21st.
Academic Offences
These will not be tolerated (See examples from UW Policy #71 which is attached). On first offence,
the offence will be reported to First Year Engineering and appropriate action will be taken. If you are
unsure of what constitutes an academic offense in UW after reading Policy #71, please contact your
instructor.
Important Information about Academic Offences
Academic integrity: In order to maintain a culture of academic integrity, members of the University of
Waterloo community are expected to promote honesty, trust, fairness, respect and responsibility.
[Check the Office of Academic Integrity for more information.]
Grievance: A student who believes that a decision affecting some aspect of his/her university life has
been unfair or unreasonable may have grounds for initiating a grievance. Read Policy 70, Student
Petitions and Grievances, Section 4. When in doubt, please be certain to contact the department’s
administrative assistant who will provide further assistance.
Discipline: A student is expected to know what constitutes academic integrity to avoid committing an
academic offence, and to take responsibility for his/her actions. [Check the Office of Academic
Integrity for more information.] A student who is unsure whether an action constitutes an offence, or
who needs help in learning how to avoid offences (e.g., plagiarism, cheating) or about “rules” for
group work/collaboration should seek guidance from the course instructor, academic advisor, or the
undergraduate associate dean. For information on categories of offences and types of penalties,
students should refer to Policy 71, Student Discipline. For typical penalties, check Guidelines for the
Assessment of Penalties.
Appeals: A decision made or penalty imposed under Policy 70, Student Petitions and Grievances
(other than a petition) or Policy 71, Student Discipline may be appealed if there is a ground. A student
who believes he/she has a ground for an appeal should refer to Policy 72, Student Appeals.
Note for Students with Disabilities
AccessAbility Services, located in the Needles Hall extension, Room 1401, collaborates with all
academic departments to arrange appropriate accommodations for students with disabilities without
compromising the academic integrity of the curriculum. If you require academic accommodations to
lessen the impact of your disability, please register with AccessAbility Services at the beginning of
each academic term.

Review for Final Exam
Excerpts from University of Waterloo Policy #71
“Student Academic Discipline Policy”
Original text available at: http://uwaterloo.ca/secretariat/policies-procedures-guidelines/policy-71
A university is a community of scholars in which knowledge is generated and disseminated through
scholarship and teaching. All members of the community – faculty, students and staff – are bound to
conduct themselves with honesty, integrity, fairness and concern for others. Any action which
unnecessarily impedes the scholarly activities of members of the University is an offence punishable
by appropriate disciplinary action.
Academic offences
Some of the academic offences outlined by the University include:
Infringing unreasonably on the work of other members of the University community (disrupting
classes or examination; harassing, intimidating or threatening others).
Cheating on examinations, assignments, work term reports, or any other work used to judge student
performance. Cheating includes copying from another student’s work or allowing another student to
copy from one’s own work, submitting another person’s work as one’s own, fabrication of data,
consultation with an unauthorized person during an examination or test, and use of unauthorized aids.
Plagiarism, which is the act of presenting the ideas, words or other intellectual property of another as
one’s own. The use of other people’s work must be properly acknowledged and referenced in all
written material such as take-home examinations, essays, laboratory reports, work-term reports, design
projects, statistical data, computer programs and research results. The properly acknowledged use of
sources is an acceptable and important part of scholarship. Use of such material without complete and
unambiguous acknowledgement, however, is an offence under this policy.
Submitting an essay, report, or assignment when a major portion has been previously submitted or is
being submitted for another course without the express permission of all instructors involved.
